SASH LOCKING AND PIVOTING- DEVICE.

Specification of Letters Patent.

Patented Mar. 21, 1916.

Application filed August 10, 1914. Serial No. 856,040.

To all whom it may concern:

Be it known that I, JAMES P. WILLIAMS, citizenof the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Sash Locking and Pivoting Devices; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in sash locking and pivoting devices for windows.

The object of the invention is to provide a simple and efficient device of this character which provides for the raising and lowering of the sash, the swinging or reversal thereof and the easy removal of the sash from the frame.

With this and other objects in view, the invention consists of certain novel features of construction and the combination and arrangement of parts as will be more fully described and claimed. y

In the accompanying drawings; Figure 1 represents a front elevation of a window equipped with this invention and with parts broken out and the connecting means for the sash and frame shown in operative position; Fig. 2 is a similar View with the sash and frame connecting means in operative position and with the pivoting elements shown in position for use; Fig. 3 is a vertical section taken on the line 3-3 of Fig. 2; Fig. 4 is an enlarged vertical section showing the sash guiding means in operative position and with the pivoting elements in inoperative position; Fig. 5 is a similar view showing the sash connecting and guiding means in inoperative position and the pivot ing means in operative position. F ig. 6 is a transverse section taken on the line 66 of Fig. 1; Fig. 7 is a similar view taken on the line 77 of Fig. 2; Fig. 8 is a front elevation of the inner face of the window frame with parts broken out and in section on the line 88 of Fig. 4; Fig.9 is an edge view of a portion of the window sash showing one of the connecting rollers.

It is well known that many accidents occur by persons washing windows which are not reversible and which necessitate the operator sitting on the sill and this is especially true in high buildings, many deaths having occurred by reason of the falling of the window washers from the upper floors of such buildings, and it is to avoid these accidents that this invention is especially designed.

In the embodiment illustrated a window frame 1 is shown having the usual stiles 2 and sill 2. On the inner face of each of the stiles 2 are secured two laterally spaced sash guides 3 and 4 which extend from the top to the bottom of the stiles and on which the sashes are adapted to slide in a manner to be described whereby the sash is held in position and the usual beads thus dispensed with. These guides 3 and 4 are preferably made of angle iron with onefiange thereof projecting laterally and disposed edgewise to engage with cooperating means carried by the sash. Each sash 5 is provided on one of its side edges with a plurality of longitudinally spaced grooved blocks 6 designed to slidably engage the laterally projecting flange of one of the guides 3 or 4 as the case may be. The other side edge of the sash 5 is provided with longitudinally spaced inwardly extending recesses or pockets 7 or 8 with a solid portion 9 arranged between them and which latter has an aperture 10 extending from edge to edge thereof, the outer end of said aperture being reduced as shown at 11 and the inner portion enlarged as shown at 12 for a purpose to be described. The outer edge of this block 9 is cut away a suflicient distance to form a seat and to house a spring metal strap 13 which is fixed intermediately of its ends to said block 9 with its free ends equipped with peripherally grooved rollers 14 which are revolubly mounted on said ends. These rollers 14 are positioned opposite the pockets 7 and 8 and are designed to be housed therein when desirable and for a purpose to be described. These peripherally grooved rollers 14 are designed to normally engage and travel on the laterally projecting flanges of the sash guides 3 and 4 on the adjacent side of the frame 1 and are normally held yieldably in engagement with said flanges by the resiliency of said strap 13.

The roller retracting means here shown is clearly shown and described in detail in my copending application Serial No. 856,039 filed August 10, 1914 and hence will only be referred to generally herein. Each roller is provided with retracting means in the form of an eye bolt 15 connected with a link 16 which extends through an aperture 17 in the rear wall of the pocket and in which said roller is to be withdrawn and the outer" end of this link 16 is connected-with a bellcrank or cam lever 18 operable when turned in one direction to retract the roller connected therewith and house it within the pocket opposite which it is disposed and'when this lever is turned in the other direction it re-, leases said link and permits the roller to be projected by the spring strap 18 into frictional engagement with the lateral flange of the sash guide. These levers 18 are fulcrumed in suitable brackets 19 mounted on the inner edge of the side member of the sash 5. The flanges of the guide members 3 and 4 which are secured to the inner faces of the stile at one side of the frame are preferably provided with a plurality of longitudinally spaced apertures 3 and l" respectively which are designed to receive the free end of the pivot member now to be described. As shown this pivot member comprises an angular shank 20 which extends through the. aperture 10 in the block 9 through the reduced outer portion 11 thereof and through an aperture llin strap 18 1 which latter is also made angular in cross section to receive said shank and hold 1t against turning for a purpose to be described.

The end of the shank which passes through the angular aperture 11 is preferably pointed to facilitate its engagement with one of the apertures in .the flange of'the sash guide and the other end thereof being provided with a cylindrical head which projects through the side member of the sash and is coarsely threaded to receive an adjusting nut 21 the turning of which on said screw threaded head retracts or projects it in a manner to be described. This nut 21 is elon-. gated to'provide a bore-0r socket therein of sufiicient length to receive the theaded end of the shank 20 and provide for its projection or retraction to a predetermined extent.

This nut 21 is provided at its inner end with an annular groove 22 to receivea supporting member 23 and whereby said nut is swiveled in connection with said plate. As shown the inner end of this nut fits within the enlarged portion 12 of the aperture 10 and the outer face of the block 9. around said aperture is-recessed to form a seat for said member 23 which is secured to the block by screws or other suitable fastening elements and by means of which the nut is supported-on the sash. As shown this nut supporting member is composed of two plates, an integral plate 2 1, and a plate composed of sections 25 and 26. The outer plate-24 has an aper: ture therein of a size to fit within the groove 22 of the nut and is provided with a slot24= leading therefrom to adapt the nut to be. inserted. The inner plate is formed of the two sections 25 and'26 which are provided on their abutting edges with registering notches vious that when the. nut 21 is turned in one direction the shank 20 will be retracted into the, socket therein and its pointed end with-..

drawn from engagement with the aperture in the guide flangeas shown in Fig. 4 while when saidnut is turned in the opposite direction said shank will be projected through the edge of the sash and into engagement with the flange of the sash guide. WVhile apertures are shown formed in the flanges of the sash guides for the reception of the ends of the shank of the pivot member it is obvious that it is not necessary that these shanks be inserted in one of the aperture as it may be held in frictional engagement with the flange but the apertures are provided to render the holding of the sash in operative position more reliable. Two of these pivoting devices are provided for each sash as is shown clearly in Figs. 1 to 3 and are preferably disposed, at points midway the length of the sash inthe side members there of and at points diametrically opposite so that whensaid devices are in operative position the sash may be readily swung on said pivot members to reverse it for cleaning the outer faces of the panes.

The usual sash retaining beads 28 are.

preferably employed on the stiles of the frame at the inner and outer edges of the. sash, guide ways "and are hinged to open outwardly into the position shown: in Fig. 7 to provide for the removal or swinging of the sash when desired.

In the operation of this device when itis desired to reverse the position of the sash for cleaning or other purposes the levers 18v are first swung inward toward each other into the position shown in Fig. 2 for retracting the rollers with which they are connected and thereby freeing the sashat this side of the window from the guides.., The pivoting device 21 at the right hand side of the sash is then turned sov as toforce theshank thereof into engagement with the sash guide on the adjacent side of the frame and a continued turning of the nut in said de-' vice will cause the sash to move bodily toward the left a sufficient distance to disengage the grooved blocks 6 thereof from the laterally projecting flanges of vthe guides 3 or 4 as the case may be. The other pivot-v ing device at the left side ofv the sash is then turned to move its shank outward'into engagement with theguide on the adjacent side of the window frame the rollers having 27 which'are adapted to register and form' The member 23 is been already withdrawn from said guides to provide suflicient space for the sash to move laterally a sufficient distance to disengage the blocks 6 from the guides at the right of the window and also to cause the side member of the sash that carries the rollers to swing clear of the guides on the adjacent side of the window frame. WVhen these pivoting devices have been so disposed the beads 28 are swung outwardly and the sash may then be swung on its pivot members into the position shown in dotted lines in Fig. 3 or they may be entirely reversed if desired and thus the window may be washed 011 both sides from the interior of the building without endangering the life of the operator. When it is desired to remove the sash these pivot members are turned to retract the shanks thereof within their nuts a suflicient distance to clear the flanges of the guide members and the sash may be easily lifted out.

To return the sash to operative sliding position it is first placed within the frame and the bead 28 swung inward to hold it against lateral movement while the guide members thereof are being adjusted. The blocks 6 are first engaged with the flanges of the guide members on the adjacent side of the window frame and the levers 18 are turned outwardly into the position shown in Fig. 1 whereby the rollers 14: are projected by the spring 13 into frictional engagement with the flanges of the guides of the adjacent side of the window frame and the sash is then ready to be moved up or down in the usual manner.

From the above description it will be obvious that this improved device may be readily disposed into either operative or inoperative position by the simple turning of the nut thereof in one direction or the other.

I claim as my invention The combination with a window-frame having stiles provided with guides, of a window-sash provided on one of its side edges with grooved blocks to slidably engage the guide on one stile, the other side edge of said sash being provided with retractable guide engaging elements, said frame being wider than the sash, and projectable and retractable pivoting devices carried by opposite side rails of said sash and engaging said uides, whereby the sash may be moved bodi y when said retractable flange engaging elements are in retracted position by forcibly engaging the pivoting device at the other side of the sash with its guide to cause said sash to clear said guide and permitting it to be swung or removed from the frame.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
